Question

Given set (7, 77, 140) then follows
1. (9, 88, 180)
2. (6, 66, 120)
3. (8, 80, 166)
4. (4, 10, 160)

Answer 1

Correct Answer - Option 2 : (6, 66, 120)

The logic followed here is:

First Number × 11 = Second Number

First Number × 20 = Third Number

7;

(7 × 11 =) 77;

(7 × 20 =) 140

Similarly,
6;

(6 × 11 =) 66;

(6 × 20 =) 120

Hence, (6, 66,120) is the correct answer.
